Characteristics and application scope of domestic water supply equipment

Fire pumps are a type of pump used in fire fighting. Compared to ordinary pumps, fire pumps have higher standards and requirements in terms of sealing, corrosion resistance and operational efficiency. Before running the fire pump equipment, we need to discharge the gas inside the pump, do you know what is the significance of doing so? The following is the answer from Shanghai Xizhiquan.

1. If there is gas inside the fire pump, then the equipment cannot form a sufficient vacuum during operation, resulting in the liquid not being able to be sucked up. This phenomenon is called gas binding, and is a phenomenon that often results from many operators not understanding this operation.
2, understand the formation of gas binding causes, we will understand how to avoid this problem occurs. Before the fire pump equipment is started, the pump casing needs to be filled with liquid. In the pump suction pipe mouth need to be equipped with a non-return valve, can effectively avoid the pump in the liquid due to gravity into the low tank, if the pump position is low, there is no need to carry out filling the pump.
3. The compressed gas inside the fire pump will occupy a certain space in the fire pump, making it impossible to seal it.

Therefore, the operation of deflating the fire pump before putting it into use can increase the vacuum of the equipment and increase the pumping capacity of the pump, thus effectively improving the efficiency of the equipment and reducing the waste of resources.

When a partial failure of the equipment occurs, the emergency function can be enabled to continue the water supply. The equipment can be automatically connected to the municipal water supply network, and has dual constant pressure functions, which can meet the normal pressure and flow of domestic and production water, and can automatically switch to high-pressure and large-flow water supply when a fire occurs, and can be used for multiple purposes.

The automatic water supply equipment automatically adjusts the number of running water pumps and the speed of a water pump according to the change of the user’s water consumption, so that the outlet pressure of the water pump remains constant.

The portable fire pump is well know for its simple structure, light weight, compact structure and high efficiency.

The fire pump refers to a clean water pump used for fire water supply, and a single pump that handles medium temperature below 80 degrees and is not corrosive. The pump set is the joint operation of multiple fire pumps to ensure the quantity and stability of the water supply. The electric motor fire pump group adopts multiple fire pumps powered by electric motors. The general fire water supply environment is equipped with one electric and one diesel fire pump as the reserve water pump to ensure sufficient emergency water consumption. The main components of the electric motor fire pump group are the motor and the pump body. The subdivision of the pump body is the pump casing, impeller, pump shaft, bearing, coupling, sealing form, water lift pipe, etc. The specific fire pump model is determined according to the environment and performance requirements, and at the same time According to the material quotation required by the customer, accurate selection is beneficial to on-site use and reduces failure problems.

Air conditioning pump systems are typically more energy-efficient than traditional air conditioning systems, especially in moderate climates. They can provide both cooling and heating, making them versatile for year-round use. They also offer zoning capabilities, allowing different areas of a building to be cooled or heated independently.
